Claims. (01. 175--356) This invention relates to transformer assemblies for floor lamps and the like and is more particularly directed toward providing a base for combined lighting appliances and ultra-violet 6 applicators designed to be used as floor lamps.

The glow lamps now available for ultra-violet lighting require'the use of a transformer to step down the current to the low voltage applied to the terminals of these lamps. Where the port- 'able applicators, such' as floor lamps, are contemplated, it is preferable to place the transformer in a lamp base and the present invention is directed toward the provision of a suitable construction for this purpose.

An object of the present invention is to provide a lamp base for the purpose" above described wherein the transformer is secured to a base or body member adapted to rest on the fioor an securely clamped in place. This base or body member also supports the standard for the lamp.

A further object of the invention is to provide a device'for this purpose wherein the lamp standard may be connected either at the center of the base or to one side of the base so that the standard for the lamp may be moved nearer the corner of a room. To this end the lamp base is preferably'm'ade square so' as to-fit into the corner. A further object of the invention is to design the lamp base so that the transformer is completely insulated from the metal parts.

Other and further objects of the invention will appear as the description proceeds.

The accompanying drawing shows, for purposes ofillustrating the present invention, two of the many embodiments in which the invention may take form, itbeing understood that the drawing "is illustrativeof the invention rather than limiting the'same. In the drawing:

7 Fig. 1 is a vertical sectional view on the broken line 1-'-1 of Fig. 5; Fig. '2 is a fragmentary view illustrating the use of the device of Fig. l as a wall bracket; Fig. 3 is a vertical sectional View on an enlarged scale showing certain of the electrical con-- nections; 4 is a top plan View, parts being in section on the line 44of Fig.1;

' Fig. 5 is an inverted plan view of the structure shown in Fig. 1;

Fig. :6 is a fragmentary section on the line 6-6 of'Fig'.5; and I Fig. 7 is a vertical sectional view through a 'modified form of construction.

The" base for ultra-violet applicators and the like shown herein has a body member 10 adapted desired, the

to rest on the Iioor. This body member is of generally square shape with rounded corners, as indicated in Figs. 4 and 5 and at the corners has downwardly extending feet 11 adapted to reach the floor.

of usual construction is shown ormer is generally rectangular ed with its diagonals parallel base. The punchings of are held together by corner =3, these bolts having clamping 15 at their ends as shown. The coils in sl ape a with the the tra nuts 1 and of the transformer indicated at 16 and 17 extending above and below the stamping.

The base 10 to accom has a depressed central portion 18 e the windings on the lower side of the tr eer and, as shown more clearly in 6, it if, provided with openings 19 adapted to receive insulating buttons 20 spaced the same as the boits-l3 the transformer. These insulating buttons have recesses 21 to receive the lower ends of bolts 13 and thereby support the transformer in place and insulate it from the base or body member.

A yoke 25 in the form of a bent sheet metal strap is shaped to receive the transformer 12 and is secured at its ends to the body member 10 by screws indicated at 26. This strap is of heavy material so as to be substantial and rigid. The transformer is clamped in place by screws 27 carried by this yoke and in order to insulate the transformer from the yoke, the insulators 28 are interposed between screws 27 and the transformer 12. Where the insulation feature is not insulators may be omitted and the ransformer clamped directly to the body member. The'bridging member or yoke 25 is apertured in the center as indicated at 29 and reoeives' a tubular member so which is adapted to receive he wires 31 and 32 and to support the lamp standard.

Where the lamp standard employs a simple length of pipe, as a conduit for wires, this tubular member 33 may be threaded to fit the pipe, or the pipe may be fastened in as indicated in Fig. 7. Where the lamp base is designed, however, for use withinterchangeable, self wiring lamp parts, such as shown in my application for patent on Lighting appliances, Serial 'No. 483,814, filed September 23, 1930, the yoke ispr'ovided with one of these fittings or outlets as indicated in Fig. 3. The secondary wires 31 and 32 from the transformer are connected to an axially disposed pin 33 a concentric tubular contact member 34 externally threaded as indicated at 35. The pin 33 fits into a metal tube 36 carried within the tubular member 34 and insulated from it by insulator 37. Washers 38, 39, and 40, and an insulating fitting 41, suitably insulate these parts and they are all clamped and secured in place by a threaded locking ring 42 received within the member 30. This fitting is the same as that shown in the application above referred to and is adapted to receive lamp standards or other parts having cooperative contacts, such, for example, as the threaded tubular conductor 43 and concentric pin 44 carried by such lamp part.

One corner of the body member 10 is provided with an opening as indicated at 50, this opening having the same interior dimensions as the tubular member 30 and being adapted to receive a fitting the same as shown in Fig. 3. This fitting is connected to the secondary of the transformer by wires indicated in dotted lines at 51, these wires being carrieddown from the secondary of the transformer through a suitably located opening in the body member as indicated.

In order to provide a finished appearance to the lamp base and protect and conceal the transformer, a cover member 53 is placed about the transformer. Its lower edge 54 fits outside a head 55 carried by the base 10 and it is clamped in place by a locking ring 56 threaded on to the tubular member 30. It carries a switch indicated at 57 preferably placed above the corner of the body member 10 which is opposite the outlet or fitting placed in the socket 50.

In order that the base may be adjusted so that the lamp standard may be vertical, it is provided with three adjusting screws 60 threaded into the corners as indicated and provided with springs 61 which make it unlikely that the screws will change adjustments once they have been placed.

When the device is in use a lamp standard may be threaded on to either of the outlets so that one can either have the lamp standard extend up from the center or from the rear corner. The unused outlet may be covered by a cap indicated at 62. The arrangement of parts makes it very convenient to place the lamp base in the corner of the room, as for example, in the bath room, and to have the standard extend up very close to the corner of the room. It can be adjusted closer to the corner if desired by means of the levelling screws. The switch 57 is above one of the corners of the base and is thereby protected against accidental in- Jury.

As occasions frequently arise where it is desirable to secure these bases to the wall instead of having them rest on the floor, the present lamp base is provided with a cross strap indicated at 65 and secured to the base by screws 66. This cross strap carries a hook member 67 secured to it by screws indicated at 68 and normally carried in the position indicated in Fig. 1. Should one desire, however, to mount the base on the wall or other vertical support, it is only necessary to remove the screws 68 and secure the hook member 67 to the wall, as indicated in Fig. 2, whereupon it will be in a position to receive the strap 65 and support the base.

In the form of construction shown in Fig. 7, the body member 70 is made round and is provided with a central opening 71 adapted to receive the transformer 72. A yoke 73 is secured to the upper side of the base 70 by screws 74 threaded into the flange 75 and the transformer is clamped in place by Z-shaped straps 76 secured to the underside of the flange 75. A pipe 77 extends ing a switch 81 as indicated. The parts are clamped together in the usual manner by a nut threaded on to the upper end of the stem 77 as customary.

It is obvious that the invention may be embodied in many forms and constructions, and I wish it to be understood that the particular forms shown are but two of the many forms. Various modifications and changes being possible, I do not otherwise limit myself in any way with respect thereto.
